(county of Kings andStatc of' New York,

hav(l invented certain new and useful lm- .provements in Reilectors; and We do hereby declare the following to be a full, clear, and exact description ol'I the ii'ivention, such as will enable others skilled in the art to which it appertains lto make and use the same, reference being had to the accompanying drawings, and to characters of reference marked thereon, which forni a part of this specification.

Our present invention relates, enerally, to improvements in reflectors; and, the invention has reference, more particularly, to improvements in that class of rellectors which are provided with a hood or holder tor the reception of an electric or other lamp-re'- cciving socket and p-rovided with means for the suspension or connection of the reflector to a stem, bracket,v or other suitable means olE support.

The present invention has for its principal object to provide a simple and novel means for retaining thek sectional reflecting elements or glasses Within the reflector-casing or shell; and, furthermore, to provide a novel construction of hood or holder for the reception of the lam -socket, aswell as a novel lmeans and nietliod of applying, the holder which supports the reflector or shade to the latter, with a View olf providing a sirnplel means of su port and connection between the relec'tor- 'iody or shade and a fitting by means of which the device is attached to a supporting stern, bracket, or the like, said parts being arranged in such a manner, so that the supporting strain, which in the brackets as now ordinarily made is brought directly upon the lam socket, is entirely remo-ved from theI 'said amp-socket.

Another principal object of our present.

invention is to providel simplicity ofconstruction and ease inthe manner 'of assembling the parts and varranging the hood or holder over a central opening in ther'electorbody or shade, and furthermore to provide a hood or holder which is formed with openings through Which'lthe fingers can be inserted for holding the lamp-socket in place while the parts are being assembled; and, also', to provide a .hood or holder which has a spring-like action, so as to be easily sprung into holding relation With the relcctor-bmly or shade and is readily detachable from the said reflector-body or shade for convenience in packing thevparts of the reflector `for shipmg. v

Other objects of this invention not at this vtime more particularly enumerated will be clearly evident from the: following detailccl dcscri tion. i

Wit the various objects of our present invention in view, the said' invention consists, primarily, in the novel reflector hereinafter set forth; and, the invention consists, furthermore, in the various arrangements and combinations of the devices and parts, as Well as in the details of the construction of the same, all of which will be fully described in the following saecification, and then'linally embodied in thev clauses of the clairnswhich are appended to and which form an essential part of this specification.

The invention consists, also, more particularly in the speciiic means of securing thel reflecting-elements or glasses within the reflector-bod or shell, the novel means and method ol applying the hood or holder which supports the rellector-body or shade from the usual supporting stern, bracket, or the like, instead of on the shell of the lampsocket; and also in the novel construction of oscillating lttinfor adjustably con-necting or suspending t 1e reflector from the suspension rod, bracket, or the like.

The invention is clearly illustrated in the accompanying drawings, in which':-

Figure 1 is a view of the complete reflector embodying the principles of the presentinve-ntion, the reflector beine' represente/.l partly in elevation and partly inl vertical section. Fig. 2 is an elevation of the hood or holder, an adjustable fitti-ng, and the u yper portion of thev reflector-body or sha( e',

said parts being shown looking in a planel at right an 'les to the plane ot view represented in said' ig. 1. Fig. 3 is a to or plan view off the ripper` open portion oV the reflectorbody, shade, or shell, they hood lor holder which supports said body or shell being z omitted from said View. Fig. 4 is a transverse vertical section taken on line 4 4 in said Fig. 2; and Fig. 4a is a detail cross-section of the joint between the connected reflector-members. Fig. 5 is a diagrammatic View ol'y a blank from which the main body or portion of said hood or. holder is made; Fig. 6 is an elevation of said main body or portion of the hood or holder rolled or forced :into its shape from the blank shown in said Fig. 5; and Fig. 7 is a top-end view of the main body or portion of the hood or holder shown in said Fig. 6, said Figs. 5, 6 and 7 being made. on enlarged scales. Fig. S is a transverse vertical sectional representation of the upper portion of the riHector-body, shade, or shell, and a sectional representation of a hood or holder, showing a modified construction of securing the hood or holdei in its fastened position over the upper open portion of the reflector-body, shade or shell.

Similar characters of' reference are employed in all ol' the above described views to indicate corresponding parts.

Referring now to the said iigures of the drawings, the reference-character 1 indicates the complete reflector made according to and embodying the principles of our present invention. The reflector-'body or shade in the present instance comprises an upper shade-membra or shell 2 and a'lower shadeineinber or shell 3', said upper shell being made with an inwardly bent marginal bead, as 4, and the lower shell being made with an outwardly bent marginal bead, as 5, over which the said bead 4 is 'fitted and firmly clamped down upon the saine, so that the two shade-members or shells 2 and 3 are securely united, as will be. clearly evident. The said bead 5 of the lower shell 3 is made withsuitahly formed and suitably disposed holding lugs or ears 6, which are bent downwardly and over thc edge-portions of suitably formed reilector-elements or glasses 7 which are iitted upon the. inner surface of the lower shade-member or shell 3, said elements or glasses-7 beingsuitably held in place by said lu s and a bead-like clamping ring 8 which is 'tted upon and clamped dircctly over the lower marginal edge of the shade-member or shell 3 and the-lower edgeportions of the reflector-elements or glasses 7, as clearly shown in Fi 1 of the drawings. T he said bead 5 of the Fewer shell 3 is also made with suitably formed and suitably disposed holding lugs or ears 9, which are bent upwardly and overthe lower` edge-portions of suitably formed reflector-elements or glasses 10 which are fitted upon they inner surface of the upper shade-member or shell 2, said elements or lasses being` suitably held in place by said. ugsory ears 9, and by a retaining ring 11 and a clamping or holding ring 12 suitably disposed in the upper central opening of thesaid upper shade- .projecting annular member or shell 2, substantially in the manner to be presently described. One manner of connecting these parts is clearly illustrated in Fig. 4 of the drawings, the retaining ring 1l comprising a downwardly and inwardly bent marginal bead 1S which is fitted over and irmly clamped upon an outwardly Y marginal edge-portion 14 of said shell 2. The said retaining ring 1 1 is made with an inwardly and downwardly extending part l5, which terminates in an upwardly extending annular marginal edgeportion or ring-shaped member 1G, the upper edge-portions ot the reileetor-elenicnts or glasses l() al.=utting slightly against the inwardly and downwardly extending part 15 of the ring 11,substantially as shown.

The holding or clamping ring 12 is prcl'crably ol` an arc-shaped cross-section, its inarginal annular edge-portion 17 projecting beneath the lower and under part olI the upwardly extending marginal edge-portion or ring-shaped member 16 ol the ring l1, and

said edge-portion 17 fitting directly upon the faces ol' the reilector elements or glasses 10, so as to securely hold the upper end-portions of said rellcctor-elements or glasses in place, as will bc clear y'iinderstood. The said holding or clamping ring 12, al'ter it has been inserted in its retaining relation with the upper shade-member or shell 2 and the ring 11 iitted thereto, in the manner just described, is dctachabl' '1,fY secured in said holding or clamping relation, by means ol' a series of holding or clamping tongues or prongs 1S which extend Vfrom the upper marginal edge of the ring .12 and arebent outwardly and directly upon the upper edge oll the upwardly extending annular marginal edge-portion or ring-shaped member 1G ol'l the ring 11, so that the various parts are securely and rigidlj,Y clamped in their assembled positions, with the upper end-portions ol' the reflector-elements or glasses 1() positively" held in place. Any one or more oi' said elements or glasses 1() can be readily removed by bending'back theholding or clamping tongues or prongs 1S, so that the ring 12 can be removed from within the uplli) lOl)

er central opening of the upper shade-memer or shell 2.

The hood or holder for attaching the rciiector to a stem, bracket, or other suitable support, is indicated by the reference character 19, the holder' shown in Figs. 1 to 7 in-l elusive, being blanked out of a piece ol' sheetnietal 20, (see Fig. 5), the saine being ici-med with a series oi projections or extensions 21,

which are made with the variously shaped arc-shaped marginal edge-portions 22, 23, 24, 25 and 26, and which, when thc vblank 20 is rolled or pressed into the shape to form the `hood or holder 19, are brought into an overlapped relation, as shown in the several ligures of the drawings, so as to provide a hollow holder, l'ormed with a lower and open cylindrical portion 27, and an upper ovoid porlend-portion oi' said hood or .dished or cupshaped cap or disk-like plate tion, as 28, formed in its end with an opening 29', and in its sides with a series of other openings 30. As shown, the said hood or holder which is th-us provided, is also made in its cylindrical portion 27, with an outwardly projecting annular bead or groove 31. The purpose of this bead or groove 31 is to force the lower split and spring-like cylindrical portion 27 directlyover marginal bead 13 of the retaining ring 11, saidbead or groove 31 being readily 'sprung or forced into its holding engagement with the bead 13, so as to positively but detachably connect thesaid hood y or holder 19 with the upper shade-member or shell 2 of the reflector, as wil-l be clearly understood. Resting directly upon the upper older 19 is a 32 which is ornamental and also serves to hold the overlapping portions of the hood or holder together, the said plate '32- being formed with a centrally disposed hole or opening 33 which registers with the hole or opening 29 .in the upper end of the ovoid portion of said hood or holder )19g/as clearlyT indicated in Fig. 4 of the drawings.

The referencc-character 34 indicates any suitably formed lamp-socket which is provided upon its u per portion with a tubular member or nipp e 35 formed with an externally sr-,rerthreaded part, substantially as shown. This lamp-socket 34 is arranged within the previously mentioned hood or holder 19', with its upper and rounded endportion bearing directly against the inner surface-portions of the overla )ping arts of the ovoid,l portion of the hoodl or ho der 19, with the screw-threaded nipple 35 extending into and through the previously mentioned l and registering holes or openings 29 and 33,

as clearly shown in Fig. 4 of the drawings, a sujiporting fixture which is provided with a screw-threaded hole or opening 38 being screwed down u on said nipple, substantially as shown, or properly and rigidly securing the said devices in their assembled relation. The said fixture 37 may also be provided with upwardly extending ears or ugs 39 which are rovided with screw-receiving holes. Anotiier fixture 40 may also be provided, said fixture `40 being formed with downwardlyextending ears or lugs 41 which are also made `with screw-.threaded holes, adapted tc be brought in juxtaposition to the screw-holes in the ears or lugs 39 of the iixture 37, so as to register with the same, and so that the ears or lugs of the res ective ixturesl 37 and 40 can be adjustab y connected by means of theshort connectin screws 42, which act both as adjusting an .tightening screws, as will be clearly undertion. Hence we `whereby a strong and durable arrangement of the various arts is clearly the result.

By slightly foosening the pivot-screws 42, the two fixtures 37 and 4() can be set at different angles,-so as to provide for the adjust ment of the reiector-shade, the screws being tightened up again after the adjustment of the reflector-shade has been made. j

A further advantage obtained by the use of the hood or' holderr 1,9 hereinabove `described, and provided with suitably disposed openings, as 30, is that thereby a means `is furnished for the finsertion of the :lingers through said openings into the interior of the hood or holder, so as to hold the lamp-receiving socket in lace while assembling the various parts in t eir rigidly connected relations.

In Fig. 8 of the drawings, we have shown slightly modified means for attaching the hood or holder tothe reflector-body orshade, and for at the same time securing the upper end-portions of the reflector-elements or glasses 10 to the inner surface of the upper shade-member or shell 2. In this construction, the retaining ring 11 is-secured in the upper open ortion of the shell 2 in the same manner as escribed irl connection with the construction shown in said Fig. 4, but the clamping or holding rin 12 is dispensed with, and the lowercylin rical portion 27 of the hood or holder 19 is made of a reduced cross-section, `so that the annular bead 31 will rest upon the upwardly extending annular marginal edge-portion or ring-sha ed member 16 of the ring 11, as clearly ilustrated in said Fi 8. Extendingfrom the lower marginalegxe of the cylindrlcal bodyportion 27 of said ood or holder 19 1s an arrangement of holding lugs or tongues 45 which are suitably bent against the upper edge-portions of the relleetorelements or glasses 10., whereby the latter are suitably secured in place, in the manner clearly shown in said Fig. 8.

We are fully aware that some changes may be made in the various arrangements and per combinations of the devices and parts, as i lof the present invention as described in t 1e foregoln' specification and as delined in the claims' w ich are a pended to said specifica- -o not limit our invention to the exact arrangements and combinabent marginal bead,
